A lot of you will be having HCG levels monitored, so I thought I'd post a list of the ranges of hcg levels for each week in the 1st trimester - as you can see, the ranges are very broad, and what is important is that *your* level doubles every 48-72 hours.

Here is the average range for the first trimester (most women will only get HCG drawn for 1-3 weeks)
  • 3 weeks LMP: 5 - 50 mIU/ml
  • 4 weeks LMP: 5 - 426 mIU/ml
  • 5 weeks LMP: 18 - 7,340 mIU/ml
  • 6 weeks LMP: 1,080 - 56,500 mIU/ml
  • 7 - 8 weeks LMP: 7, 650 - 229,000 mIU/ml
  • 9 - 12 weeks LMP: 25,700 - 288,000 mIU/ml

Some information about HCG
- it stands for 'human chorionic gonadotropin'
- it's made by cells from the placenta
- HCG of 5 or under = not pregnant, and 25+ is classed as pregnant
- the level will reach it's peak between 8-11 weeks, before starting to drop off
- once HCG reaches 1000-2000, it's possible to see a gestational sac when doing a vaginal/internal ultrasound, though most providers will want to wait until the levels are at 2000 (generally 5-6w gestation)
- HCG that isn't doubling in the 48-72 hour time frame can be an indicator of miscarriage or ectopic pregnancy
- high HCG levels from early on can be an indicator of pregnancy of multiples, or a molar pregnancy

Thanks so much. I had mine drawn at 4 w 4d and they were 205. I go back this Thursday to check them again. Not sure why, they seem smack in the middle for 4 weeks. Better to be safe though.

I guess it's just something some ob's like to do as part of their monitoring....
